this was a heinous and cowardly act. and given what we know about what took place, the fbi's investigating it as an act of terrorism. anytime bombs are used to target innocent civilians, it is an act of terror.

>> it was horrific. the bomb just took out the legs of everybody. >> it was very 9/11-ish, you know? >> when i made the turn, it was the first pop, boom, and another one, boom, and another one, boom. >> my immediate reaction was to seek cover. >> here we are in boston, just outside copley square. dealing wirth aftermath of the boston marathon bombings. the attacks on the people here have been felt in boston, in the state, around the country, and the world. we have new information for you about the investigation, about the struggles still going on in the hospitals for people dealing with serious injuries and of course the face that has captured us in the aftermath of this little boy, of little martin, 8 years old, lost his

life. we jugot word from his family, bill richard, the father running the marathon, his son, daughter, wife all came to see him. my dear son martin has died from injuries sustained in the attack on boston. my wife and daughter are both recovering from serious injuries. we thank our family and friends, those we know and those we never met for their thoughts and prayers. i ask you to continue to pray for my family as we remember mart. weep ask for your patience and privacy as we simultaneously grieve and recover. that is from the father to finish the race only to learn he lost what is most important to him, his son. his daughter was hurt, his wife. she is recovering. people are walking a block behind us to where the blast zone was, putting down flowers, stopping for moments of thought, trying to move on. simultaneously, people are

fighting for their lives in hospitals, still in critical, serious condition, many cases, and an investigation expanding every moment to figure out who did this and why, erin. >> yeah, everyone, of course, chris cuomo and erin burnett here in new york. extensive team coverage of the terror attack in boston. we are bringing you everything we know on this developing story. it's very much that, as we try to find out who was responsible and how it happened. this hour, hear from our chief medical correspondent dr. sanjay gupta talking about people fighting for their lives today. he's at brigham women's hospital in boston. many bomb victims are being treated there. cnn analyst, tom fuentes joining us boston, new information about the bomb but how it was designed. jessica yellin live from the white house. we have every angle covered as we try to find more information out. >> erin, because we obviously set the scene here by

remembering the little boy who lost his life, three lives were taken, his face kind of captures the symbolism of how harsh and painful the situation was. we're learning more about him and the family. we heard about the reaction from his father. carol costello's piece setting up exactly who this little boy was and what was lost. >> reporter: martin richard is now sadly the face of the tragedy. he was just 8 years old, a much loved boy. this is martin who, according to affiliate station whdh, ran into the street to congratulate his dad who was just about to cross the finish line. that moment of joy and triumph turned deadly for marten. i thought i saw a child laying to the left and my wife didn't see that as she later told me. i thought perhaps it was clothing or perhaps someone's limb because there was a man there missing a limb. but it -- it was surreal. >> reporter: and nearly killed his mother and sister. martin's 6-year-old sister lost her leg and their mother

suffered a severe brain injury. at their home in dorchester, candles burn, and the word "peace" scrawled on the sidewalk outside the house. martin's relatives grieving online. cousin tweeting "i love you martin, you'll be in my mind forever and ever." his aunt, martin, you're the sweetest, funniest boy, i'm going to miss you so much but now you're an angel. martin's mother is out of surgery. his little sister, in the first grade, is still in the hospital. we can only assume his dad, bill, is okay physically. but we know he's much loved and active in the community. the dorchester reporter says richard's family is, quote, deeply involved in all facets of life in door chester from from little league, to the church st. ann's parish in neponset. >> that little boy's face, his

smile, that picture of him in his communion suit, tough see what was lost. a situation that certainly would have been worse. that's perspective tough to take when we've had loss. we know, sanjay, people still in there. we know it is not over yet. words like serious, critical. what do they mean? what is up in the air? >> reporter: well, you know, in the hospital behind me, one of nine hospitals the patients were brought to yesterday, chris, there are five patients in critical condition. and part of this is semantics but, chris, the message is, they are still in intensive care unit, vital signs may be fluctuating. as you say, they are literally fighting for their lives. critical condition usually means that. several patients in serious condition as well, which is one step lower than critical condition. some patients, i can tell you,

going back and forth. some getting better. some becoming increasingly unstable. that's what's happening. i should point out as well, to your point earlier, some things worked well. a first wave of patients that arrive here, doctors tell me, within 15 minutes of the explosion, very quick, so key, chris, taking care of trauma patients. within an hour, that golden hour, all of the patients going to arrive here at brigham and women's did arrive here. one thing i'll point out. you may have heard this in case you haven't, doctors have confirmed to me that within those explosive devices, there was back and forth on whether they contained other things, such as carpenter nails and bb-like things, and the doctors did confirm that in fact is true. explosive devices did contain those things. details still coming out. we'll go inside the hospital here and learn more. >> very important reporting, sanjay. we look forward to getting it from you. benefit from your perspective,

as horrible as this is, the idea that only three lives lost when over 170 injured by crude and powerful devices shows what an amazing response there was on the ground and the hospitals. sanjay will be giving us more on what he gets from his reporting. back to you. >> the latest on the investigation, as you know, it's been rapidly developing and there are so many more questions than answers. joe johns covering the latest on the investigation for us. he's in washington. the latest information that has been -- that we have. all right. a law enforcement official telling us this was -- i want to make sure i put the quotes around where appropriate -- likely but not certain a timing device attached to the explosive device, not activated by a cell phone, someone could have set this up and left before it would have detonated. what can you tell us about that in. >> reporter: that's the sum and substance of it, likely but not certain there was a timing

device aattached to the bomb which the reporting described apparently encased in a pressure cooker and discarded there on the street, perhaps to look like trash. and talking to more than one law enforcement source now, what we're being told is the developing picture is one of fancied up pipe bomb, if you will that was really very weak in nature by substantive terms compared to ieds all across the world but placed in this location, with so many people, it caused a lot of injuries. had it been, say, petn or a stronger explosive we would have seen more casualties. being described as a primitive device with a timer on it as opposed to being triggered by a

cellular phone and that is what the authorities are working on right now. it's important to note that authorities are also telling us this information as we have it is not 100% likely but not certain, isn't 100% for sure. >> thanks very much to you, joe. they're so emphatic this is not 100%. so far they say there was no warning, nothing that could have picked up in advance something like this was going to happen ands it more difficult to find out who is responsible. ow former fbi director, tom fuentes. what is the significant information on the timing device? what does that tell you about the significance of the attack, who might have been responsible. >> first of all, timing device means one person could have done both bombs, could have set

timers to go off simultaneously and a variance of 15, 20 second. it means it didn't require multiple people to carry out the attack. but it may have a couple of people involved in it. secondly, if that's true, that a pressure cooker was used for the explosive to be placed inside, that would actually diminish the power of the bomb. it itself could become shrapnel but usually when you take a bomb if you contain it in something like that, it will tend to smoother it slightly and reduce the power. we've seen, i've been to bombings where there was some type of material wrapped around it that became a containment in and of itself. when the police bomb squad detonate a suspicious package they're using an oversized pressure cooker. also explosives in iraq where they try to put them inside cement truck, big bowl of a cement mixer, for example, that mixer ended up reducing the

amount of power of it. so that could count for 170 wounded instead of 170 dead. >> all right. tom, a quick follow on that, what is your feeling right now as to the fundamental question, domestic or forren? there's some reporting that al qaeda linked magazine "inspire" had techniques how to make a bomb matched this was done. anybody could have figured out how to do this. anything you have heard given you an indication of domestic versus foreign, inspiration or origination? >> personally, from the very beginning, i tended to lean toward domestic. i have been at international bombings overseas on several occasions running the investigation. i've been in the u.s. also running them. and what you have here is if your expertise is on middle east terrorism, every bombing tended to look like that, it has hallmarks of middle east

terrorism. if your expertise is domestic, then it's domestic. it has the hallmarks of both and neither. you don't have a group claiming credit. but on the other hand, the material being used, especially roofing nails or carpenter nails used that's how the atlanta 1996 centennial park bombing was put together, a pipe bomb with food container with nails in it and one of the nails struck a woman and killed her, and that was used as similar shrapnel to what we have, what it sounds like we have in this device, based on the doctors reporting. it could be both. still could be both. one of the things from the investigators' standpoint is they do not want to jump to i conclusion too soon because you might overlook another factor, another lead that contradicts your theory. they have to be very open-minded, objective and pursue every possibility. >> not get it in your head it's

one thing and find things that affirm that. >> from an investigator, what happens subconsciously trying to prove yourself right. >> right. we know what happens with that, obviously prior examples of that mistake. thank you very much. >> you're welcome. >> erin, obviously we're still in the questions phase. that's why investigators are asking anyone if they have video, pictures, seek out help lines, give give them information. yesterday was about resilience, first responders and witnesses turning in the face of danger, helping one another and stopping what could have been a greater loss of life. here from the people who made a difference in the boston marathon attack yesterday. >> when i made the turn, it was like the first pop, boom, and another one, boom, and another one, boom. like one after another. one big cloud of smoke, white

smoke. the other one after another after the other.

aaah! aaaaah! theres a guy on the window! do something, dad! aaaah! aaaah! what is happening? they're rate suckers. their bad driving makes car insurance more expensive for the rest of us.

i saw at least six or seven people down next to me. they protect immediate from the blast. one lady expired. one gentlemen lost both limbs, lower extremities. most and lower extremities. >> this is a big story around the world. hometown papers pubbished front pages that will go down in history. how the "boston globe" covered the story, a captivating photo of the scene "marathon terror." boston herald played it this way, headline "terror at the finish line." chris, that's just the sense of the shock and the horror that they felt in that town. >> absolutely, erin. but also important to note the response. that has become the metaphor for the boston marathon attacks how the people on the ground

responded to it. they couldn't control what happened to them but they could control their response. no question on the triage on the ground, follow-up at medical centers made the situation much different than it could have been. this is echoed by what we've been hearing from the white house. it's federal, done from the top-down, every federal law enforcement has been involved in this looking for who did, why. the tone from the white house as well from the president himself has been to be calm and somewhat ignoring of who did this and why and resolved in finding out who they are, bringing them to justice and show that america overcomes. take a listen. >> the american people refuse to be terrorized because what the world saw yesterday, the aftermath of the explosions were stories of heroism, kindness, generosity and love. exhausted runners who kept running to the nearest hospital to give blood, those who stayed to tend to wounded, some tearing

off own clothes to make tourniquets, first responders who ran into the chaos to save lives, the men and women who are still treating the wounded at some of the best hospitals in the world. >> now using the word and phrase "act of terror" may seem like a no-brainer. however the word means something, means something politically, legally, the aspect of being terrorized. it gets complicated. weave seeing play out here in real time. jessica, the first 20 hours, the white house, federal agents hesitant to call this terrorism. now we see a little bit of a shift. what's going on? >> reporter: chris, you're exactly right. and the president was giving it more time and with more time he had more information and so today, comfortable calling this a terrorism investigation because 20 hours after the attack he was comfortable that that's where this was headed.

now three hours after the attack when he spoke yesterday, they simply felt they didn't have enough information, the president did not want to get ahead of the facts. so you see enormous amount of caution from the white house and words they're choosing because overtime in the first term of the presidency there were instances where the white house was burned because either the president waited too long to speak after acts of terror in the country or they did come out and speak and gave bad information and so they've sort of tried to struggle to find the right balance here. so i think that's why you saw the president speak so cautiously yesterday and then lean into it much more heavily today, because the fbi had clearly determined that this was an act of terrorism by the time he spoke. i will point out, in addition, they're determining whether it was a malevolent act leaving open the possibility this could, maybe be the act of a lone wolf

person simply meantly unstable. i will tell you finally here in the white house they're describing the mood inside as very organized, very deliberate. the new white house chief of staff used to run the national security events and is very methodical person. it's sort of -- they know how to respond in crisis and the mood here is sort of calm and determined. chris? >> at the end of the day, the motive for the attack is secondary, obviously identifying who did it, bringing them to justice, as the primary goal. no ambivalence there. all of the assets on the ground, seeing and hearing them all day, that's very definitive. jessica yellin, thank you for the insight. >> explosions hit yards from the finish line, as people coming over for that moment of victory and achievement and accomplishment. we'll talk to one runner who finished minutes before the bombs went off. >> all of a sudden i heard a

loud bomb, everyone's head turned and we heard another boom. by the time we turned our heads you can see the smoke billowing above the building. ♪ (train horn) vo: wherever our trains go, the economy comes to life. norfolk southern. one line, infinite possibilities. to your table for a limited time! it's our seafood dinner for two for just 25 dollars! a handcrafted seafood feast made to share. first you each get salad and unlimited cheddar bay biscuits. then choose two from a wide variety of chef-inspired entrées like our new honey garlic crispy shrimp

for so many the boston marathon is a culmination of best of the all things, a chance to test themselves, to come together in city wide celebration for patriots day. it is family and fun and the sense of expectation. yesterday it all turned so wrong. as we learn more stories about how people experienced these attacks and how they respond, we understand how resilient the people involved from all over the country, not just boston, were. example, julie jeske, north dakota, an elite runner, finishes before the explosion but had to live through this and become part of a community that is literally like home. >> i finished ten minutes prior

to the blast. i had gotten my heat blanket, i had gotten my metal and food. i had to stop because my leg was starting to cramp. i was holding on to two gentlemen and i heard a loud boom. everyone's head turned and everyone heard a boom. you could see the smoke billowing. >> i said, what do you think that was? he solidified what everyone was thinking, a bomb. >> reporter: one of the things that helped people get through the situation yesterday, kept kaz ulties low was poise and calm. this is out of place, a beautiful event, so unexpected people didn't panic right away? >> we really didn't. the gentlemen who told me it's probably a bomb, his spouse must have been behind me, he said grab your stuff, we need to get out of here. we all kind of proceeded to the buses to grab our stuff. when i got to the bus line,

there weren't a lot of people in line at that point. within a matter of two to three minutes the buses, there was a lot of people lined up waiting to get bags. i felt bad for people in buses, they were getting flustered. one of the women next to me couldn't find her bag. my husband and child are at the f finish line and i don't have a cell phone. i pulled my cell phone out but they knocked down all of the towers and so we weren't able to reach her. >> reporter: people became family in a moment. did you see a lot of that? even if they were tired from the race they helped. >> you make fast friends. this woman, like i said i couldn't help her with my cell phone i gave her a hug, i said i know your family's going to be fine. i had her husband's cell number. i sent her a text, i've been praying for your family, i hope they're safe. she texted me back and said they're just fine.

>> from runners helping other runners reconnect with family to medical staff here to treat dehydration and simple things, balki becoming trauma experts. the more we hear, the more this becomes about the resolve of people here in boston. >> you don't know how you react in those situations and people react with such heroism. i want to make sure that you all are aware of big stories. first a earthquake hit southern iran. several people may have been killed in iran. it's unclear. numbers could get significantly higher. that part of the world, very difficult to get immediate answers. 7.8 magnitude quake hit an area where not a lot of people live we understand. felt 500 miles away in abu dhabi where buildings shook for 40

seconds or more. we don't know the amount of the damage. back here at home immigration debate front and center on capitol hill. already some have weighed on it in the light of what's happened in boston though no one has any idea whether it was a foreign national or american involved. a bipartisan group of senators called the gang of eight pushing its new proposal to reform immigration rules. set to formally release the plan today but postponed due to boston. the bill calls for a 13-year path to citizenship for people who entered the united states before last year. also calls for a quote/unquote secure border. i also want to show you what happened to the markets. we are up 141 points. that's a bounceback. i want to emphasize what happened yesterday the biggest one-day drop, a lot due to gold and broader market issues. after the boston bombings the market dropped another 100-plus points. investors today are, there was a bit of relief that perhaps

things could have been much worse and there was positive news in terms of the us economy. aday of joy and celebration for massachusetts and boston and people from 50 countries around the world but turned into one that will go down in infamy. we'll explain how the attacks happened with the information we are gathering minute by minute. it may feel slow to you but the goal is to find out who did it and why. the number one priority in the country. diarrhea, gas, bloating? yes! one phillips' colon health probiotic cap each day helps defend against these digestive issues with three strains of good bacteria. live the regular life. phillips'. live the regular life. if you've got it, you know how hard it can be to breathe and man, you know how that feels. copd includes emphysema and chronic bronchitis. spiriva is a once-daily inhaled copd maintenance treatment that helps open my obstructed airways for a full 24 hours.

you know, spiriva helps me breathe easier. spiriva handihaler tiotropium bromide inhalation powder does not replace fast-acting inhalers for sudden symptoms. tell your doctor if you have kidney problems, glaucoma, trouble urinating, or an enlarged prostate. these may worsen with spiriva. discuss all medicines you take, even eye drops. stop taking spiriva and seek immediate medical help if your breathing suddenly worsens, your throat or tongue swells, you get hives, vision changes or eye pain, or problems passing urine. other side effects include dry mouth and constipation. nothing can reverse copd. spiriva helps me breathe better. does breathing with copd weigh you down? don't wait to ask your doctor about spiriva.

i thought i saw a child laying to left, and my wife didn't see that as she later told me, and i thought perhaps it was clothing or perhaps someone's limb because there was a man there missing a limb. but it -- it was surreal and it was -- whoever did it was just the embodiment of evil.

>> embodient of evil. but new details on the bombings near the finish line. an official with knowledge of the situation tells cnn, one of the two bombs was placed inside a metal pressure cooker that was in a backpack. former fbi assistant director tom fuentes also tells us it could have minimized the damage of the explosive device. the boy who has become the face of the horrible act 8-year-old martin richard among three killed in the attack. he was running out to the finish line to congratulate his father. his mother and his sibling are currently getting medical treatment. and his father issued a statement thanking family and friends, those we know and those we are never met for their thoughts and prayers. i ask that you continue to pray for my family as we remember martin. we also ask for your patience and privacy as we work to

simultaneously grieve and recover. boston area hospitals discharged at least 51 of the more than 170 wounded in the attack but many are fighting for their lives. amputations performed last night. as you know, some of those are touch and go. and as they have said, there could be serial operations required on some people over the next hours and days as they fight for their lives. >> we're reporting on it because it's not over, erin. we hear it from the families. some families suffered more than one casualty. all of this, literally not even a day ago. in the afternoon, to reset the scene, one of the busiest corners of the boston marathon during the peak moment after the elite runners finished, four hours, about ten minutes in when the thick of the runners going to come. john berman takes us through a

tick tock of what we know what happened and when. take a look. >> reporter: a picture perfect monday in april, patriots day, day of the 117th boston marathon. the elite women races are take off from hopkinton on the 26.2 mile course on their way to boston's back bay. almost 2 1/2 hours later, the first elite runners start crossing the finish line, wave after wave of runners, thousands of them follow. then, about 2:50 in the afternoon, it happens. an explosion near the finish line. 12 seconds later, another explosion, about a block up a crowded boylston street. >> they were banged up. severe lacerations. amput amputees, a lot of shrapnel,

pretty big explosions. there was a lot of blood everywhere. >> reporter: emergency teams and law enforcement scramble. >> to this team now please. >> reporter: the investigation begins. two hours late, boston's police commissioner goes before the cameras. >> at 2:50 p.m., today, there were simultaneous explosions that occurred along the route of the boston marathon near the finish line the. >> reporter: governor urges the public to be cautious. >> we are asking that people stay out of crowds and calmly make their way home for they're visiting, back to their hotels. >> reporter: about an hour later, just after 6:00 p.m., the president appears in the white house briefing room. >> we're still in the investigation stage at this point. but i just want to reiterate, we will find out who did this and we will hold them accountable. >> reporter: and shortly before 9:00, the fbi. >> the fbi is taking the lead in

this investigation. it is asserting federal jurisdiction. it will be an ongoing investigation. it is a criminal investigation that is -- has potential, is a potential terrorist investigation. >> reporter: and the boston police commissioner sums up the sentiment of law enforcement -- >> this cowardly act will not be taken in stride. we will turn every rock over to find the people who are responsible for this. >> reporter: john berman, cnn, boston. >> thank you to john for that piece. we're engrossed in the investigation. what happens next? we're following the tribulations of the families fighting for their lives in the hospitals and seeing how this place will recover. yet a question haunting many in this city and country right now. what does this mean? how do ideal with this, part of a terror act is the fear. you don't want to deal with it but it's almost inescapable.

what do we do? how do we take what happened here and figure out what happens next? after the break, someone who can help answer that most difficult question. at a dry cleaner, we replaced people with a machine. what? customers didn't like it. so why do banks do it? hello? hello?! if your bank doesn't let you talk to a real person 24/7, you need an ally. hello? ally bank. your money needs an ally.

we were so excited to be here, to the marathon to see our son run, and it -- it's -- it's a war zone. >> no matter who is responsible the act of terror at boston marathon was meant to inflict serious damage but also, as any act of terrorer it's not how many it's about whether it can succeed in striking fear into hearts of many causing them not to congreat, not to live their lives in the free american way.

psychologist jeff gardere joins me pap we don't know anything, whether they're american, foreign, we don't know what they were inspired or motivated by. but there's a lot you do know. >> that's right. a common thread, whether international terrorist, domestic terrorist, someone with psychological issues they do want to strike terror but more than anything else, disrupt the lives of everyone else. and they're trying to make a statement and that statement is based on rage, it's based on anger, and they want to know the world, they want the world to know that they're making the statement and they want to be heard, even though no one is taking credit as yet. >> right. and is that in and of itself, does that say something to you, this person has not said, hey, it's me? >> yeah. what it tells me, from a psy psychological point of view someone who wants to someone to be uncomfortable. this is part of the terror. no one has come forward. we're used to that pattern and people are still off, they don't

know what to think, and in some way that's where they have power over the rest of us. >> what about the rest of us? what about the people who were there? or the people who weren't there who may be afraid? >> the most important thing for them to know is, it's okay to be afraid but don't sit on that fear. talk to other people about it. acknowledge it, but try to live your life as best as you can, because then you thwart the goal of that terrorist, and we know that if you let that fear take over, it becomes a phobia and then our lives are completely at that point side tracked or destroyed. >> that would be victory. >> live your life. >> all right. jeff, thank you very much. live your life. the chilling scene played over and over again. none of us, none of you watch, none of us, no one will ever forget the moment of the first blast where smoke was everywhere and one man running near the finish line was knocked off his feet that slow motion you have

seen so many times. you know what? he got up and finished the race. and he talked. he's 78 years old. he's next. okay, team! after age 40, we can start losing muscle -- 8% every 10 years. wow. wow. but you can help fight muscle loss with exercise and ensure muscle health. i've got revigor. what's revigor? it's the amino acid metabolite, hmb to help rebuild muscle and strength naturally lost over time.

sometimes there are moments that become meaningful in situations like there is. certainly, the one we're about to show you is something you've seen and is so instructive of the symbolism of this event. the explosion goes off, old man seems to get hit by blast that knocks him off of his feet. it became a moment not because bill iffrig, 78, fell down but because of what happened when he got up and what he decided to do and what he decided to say. he spoke to our piers morgan. take a listen. >> well, i was just approaching the last straightaway to the finish line and i had a good day and i'm feeling really good and i got down within about 15 feet of the finishing apron and this tremendous explosion, sound like a bomb, went off right next to me and shockwaves hit my whole body and my legs just started jittering around. i knew i was going down.

and i ended up down on the blacktop and i didn't feel any severe pain but as i rolled over, i seen a little scratch on my leg. but nothing too bad. so i laid there just momentarily and one of the finishers finishers, assistants come over and talked to me and asked me if there was anything they could do, and offered to get me a hand, help me get up and helped me get over the finish line. so i completed my race. so we did that, and i felt okay. so i told them i was probably all right. he insisted on getting a wheelchair over there. so we started to do that, but then before they had one rounded up, i said, hey, i'm only -- my hotel is six blocks away. i think i can make it okay. so they let me get out of there and i went on home to my wife. >> certainly sport here transcended, became just about the human spirit, about the attacks. and mr. iffrig really

personalizes that and personifies it. you know who else thinks so? "sports illustrated," their cover this week is bill iffrig. the headline is obvious. boston, and their magazine is about sporting and sporting life but he means so much for him to get up and finish the race and speak with confidence about living his life as the interview you just had said, that's what it is all about, right? >> it is what it is all about. right after that interview finished, he said we have to be like that man, you have to get up and finish the race, which i thought was a poignant way to talk about this. chris, of course, as you know, investigators are spending 100% of their efforts now to find the person or people because we still don't know if it was single or multiple behind the bombing. they're trying to look at personal photos and video. there is so much from that from regular people there at the finish line. coming up, what you can do to help.

chris cuomo in boston with the latest of cnn's team coverage of the attacks at the boston marathon. law enforcement this morning very clear that the early stages of their investigation asking anybody to come forward with video or pictures if they have it themselves or know someone else who may have it to help fuel this investigation.

so, our tom foreman did a story of what truth may be hidden in these photos. >> reporter: while public attention focused largely on images of the twin explosions and their aftermath, investigators are more interested in this, the pictures of what happened before the blast. >> i think we're processing all the digital photographic evidence we possibly can right now as quickly as possible with resources from fbi headquarters, quantico and that's a priority of the investigation right now. >> reporter: law enforcement official tells cnn so far investigators have found no surveillance video of anyone planting either bomb. but it is early, investigators are still combing local businesses to collect all security camera videos for blocks around, and asking people along the route to hand over any and all digital images. >> it is our intention to go through every frame of every video that we have to determine exactly who was in the area. this is probably one of most well photographed areas in the

country yesterday. >> reporter: visitors to the city are also being asked to offer up their images from the event before they leave town. >> there is a lot of questions going on amtrak and now at logan. people leaving, because everyone was there taking pictures you may have seen someone. >> reporter: before it is all done, investigators could wind up with tens or hundreds of thousands of still pictures and many, many hours of video. but the painstaking analysis of all those images is anchored on one hope that somewhere in all of that right now is a picture of the person or persons who planted the bombs. tom foreman, cnn, washington. >> that's the hope for investigators. our thanks to tom foreman. they'll get some media, they'll find something that will lead to who did this and why. a lot of unanswered questions. i can't do a lot of reporting when i'm on tvgs. i'm going to get back out there and see what we can figure out, come back on later with it. over to you now, erin. >> thank you, chris.
